Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carton manufacturing, and particularly relates to an environmentally-friendly carton box type design method and system. BACKGROUND

[0002] In the current field of environmentally-friendly carton manufacturing, in the face of changing market demand and technical challenges, how to efficiently use existing design assets and adapt to new production environments has become a common concern in the industry. Traditionally, manufacturers will accumulate a large number of modular design components in order to quickly respond to customers' customized needs. However, when the design target changes fundamentally, such as from single commodity packaging to multi-category commodity aggregation packaging, these seemingly rich component libraries often reveal their limitations in actual application, especially in the context of new automated production environments and unstable raw material supply.

[0003] Simply "piecing together" new master packaging box designs from existing module libraries, or replacing materials based on experience alone, has not been effective. A new structure that seems to have solved the problem of crushing on an automated packaging line may result in a significant decline in production efficiency due to the need for new molds; and choosing not to change the mold in order to maintain production efficiency will result in frequent damage to the master packaging box during automated operation. The core of the problem is that although the existing modular design system is large, the complex mapping relationship between its internal parameters (such as material properties, structural geometry, production process) and external environment (such as instantaneous stress of automated operation, material supply fluctuations, internal efficiency targets) becomes blurred and difficult to predict.

[0004] Therefore, when automated packaging equipment produces instantaneous and local high-pressure stress, and environmentally-friendly material supply is volatile, how to establish a design method that, without large-scale mold remaking, derives an optimization path for minimal adjustment of existing modular sub-components, to meet new functional requirements while maximizing the use of existing design assets and production resources, and to ensure that the box type maintains structural integrity under complex and changing external conditions, is a technical problem that needs to be solved.

BRIEF DESCRIPTION OF DRAWINGS

[0009] Figure 1 is a flowchart of an environment-friendly carton box type design method provided by the present application; DETAILED DESCRIPTION

[0010] The technical solutions in the present application will be described clearly and completely in the present application combined with the drawings in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments. The components of the present application described and shown in the drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0011] It should be noted that similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Meanwhile, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0012] The traditional existing environmental protection carton box type design method has the problem that the key stress area of the main packaging box is easy to be damaged when coping with automatic packaging operation. Specifically, when the mechanical arm performs grabbing and placing operation, it will produce instantaneous and concentrated high pressure stress on the box body, causing the box structure to wrinkle, crush or tear. Such structural damage not only affects the integrity of the packaging box, but also may cause damage to the internal goods, thereby affecting the transportation safety and user experience of the product. In addition, the existing design method is difficult to quickly adapt to new stress conditions under the constraints of material supply fluctuation and production efficiency, resulting in prolonged design cycle and increased production cost.

[0013] For example, assume an e-commerce retail enterprise adopts an automated sorting and packaging line, in which multi-axis mechanical arms are responsible for aggregating and placing goods of different sizes and shapes into main packaging boxes. When the mechanical arm performs "grab-move-place" actions, especially when pushing goods into specific positions within the box, it will exert instantaneous, local high-strength clamping force and pushing force on the internal partitions or support structures of the main packaging box. These forces concentrate on specific areas of the box body, such as the junction of the partitions and the walls or the edges of the internal support points. The existing design method is mainly based on uniform static load testing and cannot accurately predict and cope with such instantaneous local high pressure stress. Therefore, even the internal structure that has passed static testing may have structural deformation or failure in these key stress areas on the actual automated packaging line, resulting in a risk of structural integrity of the packaging box before transportation.

[0014] If the above problems are not solved, the main packaging box will continue to face the risk of structural damage in automated packaging operations, which directly leads to the possibility of structural defects in the packaging box before transportation. Such defects will reduce the protection of the packaging box for the internal items, increase the probability of damage to the items during transportation, and thus cause customer complaints and returns, damaging the reputation of the enterprise. At the same time, frequent damage to the box will increase the consumption of packaging materials and the rate of waste, increasing production costs. In addition, temporary repairs or design adjustments to address these problems will result in increased downtime of the production line, reducing overall production efficiency, and may require additional manpower, further affecting the operational efficiency of the enterprise.

[0015] When facing the above problems, the first thought of the present application is to increase the overall material thickness of the main packaging box or change the corrugation type to improve its compression resistance. However, this method will result in an increase in material costs and may require the re-production or modification of existing molds, thereby prolonging the production cycle and reducing production efficiency. In view of this, the present application further considers whether it is possible to enhance the impact resistance of the main packaging box without significantly changing the overall box structure and mold.

[0016] Another solution considered by the present application is to fill the main packaging box with cushioning materials. However, this solution will increase the packaging volume and weight, increase logistics costs, and may not meet environmental requirements. In addition, the placement and fixation of the filling materials also have operational complexity on the automated production line.

[0017] After in-depth analysis, the present application realizes that the core of the problem lies in the fact that the main packaging box, under certain packaging operations, its key stress areas bear instantaneous and concentrated high pressure stress. Therefore, the solution should focus on these key stress areas, absorbing impact energy through local optimization, rather than over-designing the entire box. The present application proposes that available cushioning components can be selected from the existing mold library and integrated into these key stress areas. This method can utilize existing design assets and production resources, avoid mold re-production, and at the same time improve the local impact resistance of the box. Through performance verification and cyclic adjustment of the box type after integrating the cushioning components, it can be ensured that the final design meets the preset performance standards, and finally generates instructions that can guide production.

[0018] The following will introduce and explain in detail a kind of environmentally friendly carton box type design method and system provided by the embodiment of the present application through the following specific embodiments.

[0019] With reference to Figure 1 The embodiment of the present application provides a kind of environmentally friendly carton box type design method, comprising the following steps:

[0020] S1, obtain the packaging operation of the main packaging box, and determine the key stress area of the main packaging box under the packaging operation.

[0021] The key stress area is an area on the main packaging box that is instantaneously and concentratedly stressed under the packaging operation. The application can identify the high stress concentration part by mechanical analysis, finite element simulation or actual test, and the purpose is to identify the weak link of the main packaging box that is prone to structural damage in the automatic packaging process, and to provide a basis for subsequent targeted design.

[0022] As a possible implementation manner, the application can obtain the position, attitude, instantaneous force size and direction information of the end effector of the mechanical arm performing the packaging operation. Further, the spatial distribution information of the placed articles in the main packaging box, and the contact point information with the inner wall or internal partition of the main packaging box are obtained; the spatial distribution information includes the actual spatial position, size and shape of the articles. According to the mechanical arm operation parameters, the spatial distribution information and the contact point information, the force transmission path in the main packaging box structure is dynamically calculated, and the instantaneous local high pressure stress concentration area is identified, to obtain the key stress area.

[0023] The instantaneous force size and direction information refers to the force size and direction of the end effector of the mechanical arm at a specific time point when it contacts the main packaging box or the articles inside. This can be obtained by direct measurement through a force sensor, or calculated through the kinematics and dynamics model of the mechanical arm. The purpose is to accurately simulate the external load applied by the mechanical arm to the packaging box.

[0024] The contact point information refers to the specific position of the physical contact between the placed articles in the main packaging box and the inner wall or internal partition of the main packaging box. This can be determined by a visual recognition system, a tactile sensor or a pre-set article placement model. The purpose is to clearly determine the application point and support point of the internal load, so as to accurately analyze the transmission of internal force. The dynamic calculation of the force transmission path in the main packaging box structure refers to the establishment of a mechanical model of the main packaging box and its internal articles, to simulate the transmission process of force in the box structure over time under the instantaneous load applied by the mechanical arm and the interaction of the internal articles. This can be achieved by using finite element analysis, discrete element method or multi-body dynamics simulation technology. The purpose is to reveal how the internal and external forces of the main packaging box affect each other during the packaging operation, and how the force spreads and concentrates in the structure. Identifying the instantaneous local high pressure stress concentration area refers to finding the local area in the main packaging box structure where the stress value is much higher than the average level at a specific moment, according to the calculation results after dynamically calculating the force transmission path. These areas are usually weak points of the structure or key points of stress concentration. The purpose is to accurately lock the parts that need to be strengthened and protected, to optimize the integration of the cushioning components.

[0025] S2, according to the geometric characteristics and stress characteristics of the key stress area, screening the available cushioning components from the mold library.

[0026] Among them, the buffer assembly refers to a structure unit capable of absorbing or dispersing impact energy, which can be made of a liner, a partition or a filler made of corrugated paperboard, foam material or special structure paperboard, and its purpose is to dissipate energy through its deformation or collapse when the key stress area is impacted, thereby protecting the structural integrity of the main packaging box and the internal articles.

[0027] The mold library refers to a database containing various buffer assembly design schemes and their corresponding production mold information, which can be a digital management system, in which the parameters of buffer assemblies of different shapes, sizes, materials and mechanical properties are stored, and its purpose is to provide reusable design assets to select suitable buffer assemblies that can be directly produced according to the characteristics of the key stress area, thereby improving design efficiency and reducing mold development cost.

[0028] As a possible implementation manner, the application can obtain the geometric parameters of the key stress area and the expected instantaneous pressure threshold. Further, the geometric parameters, mechanical property data and associated mold information of each buffer assembly in the mold library are queried; according to the geometric parameters and the expected instantaneous pressure threshold of the key stress area, the geometric parameters and the mechanical property data of each buffer assembly are compared, and the buffer assemblies whose geometric parameters and mechanical property data meet the comparison condition are selected, and it is confirmed that the selected buffer assemblies can be produced by using the existing mold.

[0029] Among them, the associated mold information refers to the corresponding relationship data between the buffer assembly and the specific production mold, which can be represented by mold number, mold type, mold size range, mold applicable material and other information, and its purpose is to clarify whether each buffer assembly has a corresponding production mold and the detailed attributes of these molds;

[0030] Confirming that the selected buffer assembly can be produced by using the existing mold means that after the buffer assembly that meets the geometric and mechanical property requirements is preliminarily selected, it is further checked whether these buffer assemblies can be produced by the existing mold, which can be realized by querying whether there is an effective mold number in the associated mold information, comparing the available state of the mold in the mold library, or by the system automatically matching the production compatibility of the mold and the assembly, and its purpose is to ensure that the selected buffer assembly meets the performance requirements while maximizing the reuse of existing production resources, avoiding additional mold development cost and time.

[0031] In some preferred embodiments, particularly when a new type of main packaging box is to be designed with a cushioning assembly, first, the system can automatically or by the designer input the geometry parameters of the key stress area inside the main packaging box, such as the length, width, depth and shape characteristics of the area, when the main packaging box is on the automated packaging line, for example, when the mechanical arm picks up or places the goods, and the expected instantaneous pressure threshold of the area, such as the maximum instantaneous pressure value that can be reached under a certain operation.

[0032] Subsequently, the system can access the pre-established mold library. The mold library stores detailed information of a large number of different types of cushioning assemblies, including their geometry parameters (such as size, shape, thickness), mechanical performance data (such as compression strength, energy absorption curve, elastic modulus) and mold information related to the production of these cushioning assemblies, such as the unique number of the mold, the type of the mold (such as a die-cutting mold, a pressing mold), the current available state of the mold and the applicable material range of the mold.

[0033] Then, the system can compare the geometry parameters of the key stress area obtained earlier with the geometry parameters of each cushioning assembly in the mold library, for example, by a three-dimensional model matching algorithm or a size range matching, to screen out compatible cushioning assemblies in terms of geometry size and shape. At the same time, the system can compare the mechanical performance data of these compatible cushioning assemblies according to the expected instantaneous pressure threshold, for example, by simulation or table lookup, to screen out cushioning assemblies that can withstand or effectively absorb the instantaneous pressure. In this screening process, the system can further check the mold information associated with these cushioning assemblies that meet the geometric and mechanical performance conditions. For example, the system can automatically query the available state of the corresponding mold in the mold library to confirm whether these molds are existing and available molds or need to be newly developed or customized molds. Only those cushioning assemblies that meet the performance requirements and can be produced by using existing molds will be finally screened out for the designer to choose or the system to automatically integrate into the main packaging box design.

[0034] S3, integrate the cushioning assembly into the key stress area, so that the cushioning assembly absorbs the impact energy of the key stress area.

[0035] Among them, integrating the cushioning assembly into the key stress area means that the screened cushioning assembly is installed or embedded into the key stress area of the main packaging box through physical connection, adhesion or structural cooperation, which can be achieved by buckling, gluing or pressing, etc., and the purpose is to make the cushioning assembly play its energy absorption function when stressed, to ensure that the impact energy is borne by the cushioning assembly rather than the main packaging box body structure.

[0036] As a possible implementation manner, the application can acquire the hygrothermal response characteristic data of the buffer assembly, the heat characteristics of the heat processing station, and the load characteristics. Further, according to the hygrothermal response characteristic data, the heat characteristics, and the load characteristics, the physical property attenuation of the local region of the buffer assembly after heat processing at the heat processing station is predicted, and the enhancement effect required to compensate for the physical property attenuation is determined; according to the enhancement effect, the heat-activated solidification enhancement material is selected, and the heat-activated solidification enhancement material is applied to the local region of the buffer assembly; the heat-activated solidification enhancement material is activated by using the heat generated by the heat processing station, so that the heat-activated solidification enhancement material is solidified; the solidification state of the heat-activated solidification enhancement material is monitored, and the process is adjusted according to the solidification state, so as to ensure that the buffer assembly deforms controllably to absorb impact energy when subjected to instantaneous local high-pressure stress.

[0037] The hygrothermal response characteristic data refers to the change rule of the physical parameters such as mechanical properties, dimensional stability, and hygroscopic expansion rate of the buffer assembly under different temperature and humidity conditions, which can be obtained by experimental testing, material database query, or finite element simulation analysis.

[0038] The heat characteristics of the heat processing station refer to the parameters such as temperature distribution, heating time, heat transfer mode, and heat fluctuation range provided by the station when the buffer assembly is heat treated on the production line, which can be obtained by real-time monitoring of thermocouple array, scanning of infrared thermal imager, or recording of preset process parameters.

[0039] The load characteristics refer to the dynamic stress information such as instantaneous pressure, stress distribution, action duration, and impact frequency of the buffer assembly in actual application, especially when it is operated by a mechanical arm or impacted by transportation, which can be obtained by using a pressure sensor array, a high-speed camera combined with image analysis, or simulation.

[0040] The physical property attenuation refers to the degree of decline of key physical properties such as strength, toughness, elastic modulus, or energy absorption capacity of the buffer assembly relative to its original state after heat processing, which can be evaluated by pre-post comparison test, material performance model prediction, or non-destructive testing.

[0041] The enhancement effect refers to the degree and target of improving the specific physical properties of the buffer assembly by external means to compensate for the physical property attenuation, which can be quantified by setting target strength value, energy absorption threshold, or deformation resistance coefficient.

[0042] The heat-activated solidification enhancement material refers to a composite material that can react and solidify at a specific temperature to improve the physical properties of the base material, which can be of the types such as thermosetting resin, shape memory polymer, or nano-composite coating.

[0043] The curing state refers to the degree of progress of the internal chemical cross-linking reaction of the heat-activated curing reinforcement material under the action of heat, including the transition process from liquid to gel to solid, which can be evaluated in real time by dielectric analysis, differential scanning calorimetry or viscosity monitoring, etc.

[0044] The adjustment process refers to dynamically modifying the process parameters such as temperature, time, pressure or material application amount in the heat processing process according to the monitoring results of the curing state, which can be realized by closed-loop feedback control system, expert system or preset adjustment rules, etc.

[0045] Controllable deformation refers to the ability of the buffer assembly to deform according to the preset mode and range when subjected to instantaneous local high pressure stress, such as folding, crushing or local yielding, thereby absorbing impact energy, rather than irreversible structural damage, which can be ensured by structural design, material selection or preset geometry, etc.

[0046] In some preferred embodiments, the application is implemented as follows. When the buffer assembly is integrated into the key stress area, so that the buffer assembly absorbs the impact energy of the key stress area, the hygrothermal response characteristic data of the buffer assembly can be obtained first, such as by conducting compression tests on pulp molded cushioning pieces in different temperature and humidity environments, and recording their mechanical property curves under different environments. At the same time, the heat characteristics of the heat processing station are obtained, such as by installing temperature sensors at the carton forming and bonding stations, and recording the average temperature and temperature fluctuation range of the station during the production process. In addition, the load characteristics are obtained, such as by simulating the mechanical arm grabbing and placing action, and using pressure sensors to measure the local pressure distribution and duration of the buffer assembly under instantaneous impact.

[0047] According to these obtained data, the material mechanics model or machine learning algorithm can be used to predict the possible amount of decay of the compressive strength and energy absorption capacity of the specific areas (such as the edges or corners in contact with the mechanical arm) of the pulp molded cushioning piece after passing through the heat processing station. Based on the predicted decay, it can be determined that the compressive strength of these areas needs to be increased to more than 95% of the original strength as the required reinforcement effect.

[0048] According to this reinforcement effect, a heat-activated polyurethane prepolymer can be selected as the heat-activated curing reinforcement material. This material has a certain flowability at room temperature, but will rapidly cure and form a high-strength polymer at a specific temperature. Then, by spraying or dispensing, the polyurethane prepolymer is precisely applied to the edge and corner areas of the pulp molded cushioning piece where physical property decay is predicted to occur.

[0049] Then, when the buffer assembly enters the hot processing station with the carton for bonding or drying, the heat generated by the station (e.g. 120°C) will activate the polyurethane prepolymer applied on the buffer piece to cause a curing reaction. During the curing process, the curing state of the polyurethane prepolymer can be monitored in real time using an infrared thermometer or a dielectric sensor, such as monitoring its temperature change or dielectric constant change. If it is monitored that the curing speed is too slow or the curing is incomplete, the heating time or temperature of the hot processing station can be immediately adjusted, such as extending the heating time or slightly increasing the temperature, to ensure that the polyurethane prepolymer is fully cured. In this way, it can be ensured that when the pulp molded buffer piece is subjected to a transient local high pressure stress, its reinforced region can maintain sufficient strength and toughness, and the expected controllable deformation occurs, thereby absorbing impact energy and protecting the internal items.

[0050] In one design, the present application can also set a geometric structure in a specific area of the buffer assembly, which can be folded or crushed when subjected to a transient local high pressure stress, so that the buffer assembly absorbs impact energy.

[0051] Wherein, the geometric structure refers to a structural unit with a specific shape and arrangement formed on the surface or inside of the buffer assembly, which can be realized by indentation, line, perforation, pre-made fold, or internal cavity, etc., and its purpose is to deform according to the preset path when subjected to external impact, thereby dissipating energy.

[0052] Foldable or crushable refers to the geometric structure that can undergo controllable, inelastic deformation, such as structural buckling, interlayer separation or material compaction, when it reaches a certain stress threshold, which can be achieved by designing the wall thickness, material strength, and strength of the connecting points of the geometric structure, and its purpose is to convert impact energy into structural deformation energy, thereby reducing the impact force transmitted to the protected items.

[0053] Specific area refers to a predetermined area on the buffer assembly that is expected to be subjected to a transient local high pressure stress in actual application, which can be identified through mechanical analysis, simulation or actual test, and its purpose is to deploy energy absorption mechanisms to the position that needs protection, thereby improving the efficiency and pertinence of energy absorption.

[0054] As a possible implementation manner, the physical property of the carton material is acquired in the process of setting the geometric structure, and the process parameters of the geometric structure setting process are monitored. After the geometric structure is set, the geometric features of the set geometric structure are measured; the controllable deformation characteristics and the energy absorption performance of the geometric structure are evaluated according to the physical property of the carton material, the process parameters and the geometric features; and if the controllable deformation characteristics or the energy absorption performance of the geometric structure does not meet the preset requirements, the setting parameters of the geometric structure are adjusted or the geometric structure is locally corrected to ensure that the controllable deformation characteristics and the energy absorption performance of the geometric structure meet the preset requirements.

[0055] The physical property of the carton material refers to the inherent mechanical and physical properties of the carton material, which can be the compressive strength, the elastic modulus, the tear resistance, the density, the thickness or the moisture absorption, etc., and is used to provide basic data for the design and performance evaluation of the geometric structure.

[0056] The process parameters of the geometric structure setting process refer to the operation conditions and control variables involved in the manufacturing or processing of the geometric structure, which can be the cutting depth, the indentation force, the laser power, the processing speed or the mold pressure, etc., and are used to affect the forming accuracy and structural integrity of the geometric structure; the geometric features of the set geometric structure refer to the actual size, shape and spatial layout of the geometric structure after forming, which can be the angle of the folding line, the depth of the indentation, the size of the hole, the wall thickness or the spacing of the structural unit, etc., and are used to reflect the accuracy and final form of the geometric structure processing.

[0057] The controllable deformation characteristics refer to the ability of the geometric structure to deform according to the expected mode and path under external load, which can be folding, crushing or bending under a certain pressure, and are used to ensure that the geometric structure can stably and predictably play a role in absorbing impact energy. The energy absorption performance refers to the ability of the geometric structure to dissipate or store impact energy during deformation, which can be the energy absorption efficiency per unit volume or unit mass, and is used to quantify the buffering effect of the geometric structure on impact; the preset requirements refer to the performance targets or standards set for the geometric structure in the design stage, which can be the minimum energy absorption value, the maximum deformation amount or the deformation mode under a certain load, and are used as the basis for evaluating whether the geometric structure is qualified; the setting parameters of the geometric structure refer to the input variables used to control the processing process of the geometric structure, which can be the shape of the mold, the cutting path, the layout of the indentation line or the pretreatment conditions of the material, and are used to change the final performance of the geometric structure by adjusting these parameters; the local correction refers to the small-range and targeted adjustment or repair of the formed geometric structure, which can be secondary compaction, filling, cutting or bonding of local areas, and is used to correct the deviations of the geometric structure in the processing process to make its performance meet the preset requirements.

[0058] In one design, after setting the geometry in a specific region of the buffer assembly, the application can also apply a pre-set local probing load to the set geometry; obtain local response data of the set geometry under the local probing load; evaluate the consistency of the controllable deformation characteristics and energy absorption performance of the geometry according to the local response data; if the evaluation result shows that the consistency does not meet the requirements, then perform local correction processing on the set geometry to make the controllable deformation characteristics and energy absorption performance of the geometry meet the consistency requirements.

[0059] Among them, the pre-set local probing load refers to the force or pressure defined in advance and applied to the specific region of the geometry. It can be realized by controlled impact, local static pressure or dynamic load simulating specific stress events. Its purpose is to simulate the local stress conditions in actual use and provide controllable input for performance evaluation.

[0060] The local response data refers to the measurable physical reactions of the geometry under the action of the local probing load. This can include deformation amount, stress distribution, energy absorption value or acoustic emission data. Its purpose is to provide quantitative information of the stress behavior of the geometry to support performance evaluation.

[0061] Evaluating the consistency of the controllable deformation characteristics and energy absorption performance of the geometry refers to the process of comparing the measured local response data with the pre-set design specifications or target performance standards. Consistency represents the matching degree of actual deformation behavior and energy absorption capacity with expected characteristics. Its purpose is to identify the deviation from the design performance.

[0062] Local correction processing refers to targeted adjustment or modification of the geometry or its immediate vicinity. This can involve local re-pressing, material addition, material removal or reshaping through hot pressing. Its purpose is to realign the actual performance of the geometry with the required controllable deformation characteristics and energy absorption performance.

[0063] In some preferred embodiments, the application is implemented as follows. After setting the geometry in a specific area of the cushioning assembly, for example pressing a preset V-shaped groove or wavy structure on a specific folding line of the corrugated board, in order to verify the performance consistency of these structures, the following steps can be taken. First, a preset local probe load is applied to the geometry that has been set. This can be done by a small pneumatic impact device, the end of which is equipped with a probe that matches the contact area of the geometry, to impact the key points of the geometry at a preset force value and impact speed. Then, the local response data of the geometry that has been set under the local probe load is obtained. For example, the dynamic deformation process of the geometry during the impact process can be captured by a high-speed camera, and its maximum deformation, deformation rate and folding or crushing mode can be extracted by image analysis software. At the same time, micro strain sensors can be arranged near the geometry to monitor the internal stress changes in real time. According to these local response data, the consistency of the controllable deformation characteristics and energy absorption performance of the geometry is evaluated. Specifically, the measured deformation curve, energy absorption peak value and stress distribution diagram are compared with the pre-set standard curve or qualified range. For example, if the geometry fails to fold according to the preset path under impact, or its energy absorption value is lower than a certain percentage of the design threshold, it is considered that the consistency does not meet the requirements. If the evaluation result shows that the consistency does not meet the requirements, the geometry that has been set is subjected to local correction processing. This can be done by an accurately controlled laser ablation system to remove a small amount of material from the areas of the geometry that are too hard or not deformed enough, to reduce its local stiffness and make it easier to deform controllably; or for areas with insufficient energy absorption, a thin layer of reinforcing material can be applied at specific locations by means of micro-spraying or dispensing to improve its toughness and energy absorption capacity. In this way, it can be ensured that the geometry on each cushioning assembly can stably achieve its expected impact energy absorption function.

[0064] Through the above technical solutions, the application can effectively solve the problem of inconsistent controllable deformation characteristics and energy absorption performance caused by fluctuations in the physical properties of carton materials and deviations in the manufacturing process of the geometry. By applying a preset local probe load to the geometry that has been set and obtaining local response data, the true performance of the geometry under actual stress can be accurately captured. Based on these data, consistency evaluation can be performed to timely discover and quantify the deviation between the geometry and the design expectation. When the evaluation result shows that the performance does not meet the requirements, targeted local correction processing can directly correct the performance defects of the geometry, so that its controllable deformation characteristics and energy absorption performance meet the requirements. This ensures that the geometry on each cushioning assembly can stably absorb impact energy, thereby improving the overall performance of the cushioning assembly and the impact resistance of the carton under complex packaging operations, and ensuring the safe transportation of goods.

[0065] S4, verifying the performance of the main packaging box type after the integration of the buffer assembly, and cyclically adjusting the integration scheme according to the performance verification result until the main packaging box type meets the preset performance standard.

[0066] The cyclically adjusting the integration scheme means that the type, size, position, material or integration method of the buffer assembly is iteratively optimized according to the performance verification result. It can be a cyclic process of design-test-correction multiple times, and the purpose is to ensure that the main packaging box type after the integration of the buffer assembly can meet the preset performance standard, such as compression strength, impact resistance or durability, so as to meet the needs of actual application.

[0067] As a possible implementation manner, the application can obtain the mechanical property data of the carton material corresponding to the main packaging box under multiple different temperature and humidity conditions, and identify the critical environmental condition of the carton material; under the critical environmental condition, the performance of the main packaging box type after the integration of the buffer assembly is tested to obtain the performance test result; according to the performance test result, the integration scheme is cyclically adjusted until the main packaging box type meets the preset performance standard under the critical environmental condition.

[0068] The mechanical property data refers to the physical response characteristics of the carton material under different external loads, such as compression strength, bending strength, tear strength, moisture absorption expansion rate, and modulus change under different temperature and humidity, which can be measured by universal material testing machine, paperboard bursting strength tester, ring pressure strength tester and other equipment, or obtained by finite element analysis and other simulation methods.

[0069] The critical environmental condition refers to the temperature and humidity combination in which the mechanical properties of the carton material show the worst or close to the worst state, which can be determined by systematically testing the carton material under a wide range of temperature and humidity, such as high temperature and high humidity, low temperature and low humidity, high temperature and low humidity, and analyzing the change trend of key mechanical indicators such as strength and toughness, so as to determine the specific temperature and humidity point or interval with performance decline or increased failure risk.

[0070] The performance test refers to a series of physical tests on the main packaging box type after the integration of the buffer assembly, which simulates the actual transportation and storage process. It can use drop test, vibration test, stacking test, impact test or simulated transportation test to evaluate the structural integrity, buffering effect and protection ability of the main packaging box under specific environmental conditions.

[0071] The integration solution refers to the specific design and manufacturing details of the combination of the cushioning assembly and the primary packaging box, which can include the material selection, geometry, size, thickness, internal structure (e.g., corrugation type, honeycomb structure) of the cushioning assembly, as well as its precise location, fixation method, connection method with other parts of the box, etc. within the primary packaging box.

[0072] The preset performance criteria refer to the minimum requirements or target values that the primary packaging box needs to achieve in specific performance tests, which can include that the box has no obvious deformation or damage after drop test, can withstand a certain load without crushing in stacking test, the internal article displacement is within the allowed range in vibration test, or the energy absorption efficiency of the cushioning assembly reaches a certain percentage in impact test, etc.

[0073] In some preferred embodiments, the application is implemented as follows: assuming that a main packaging box for an automated packaging line is to be designed, which has a cushioning assembly integrated inside to protect fragile items. First, the mechanical property data of the corrugated paperboard material used for the main packaging box can be collected under different combinations of temperature (e.g. -20°C, 23°C, 50°C) and humidity (e.g. 30% RH, 50% RH, 90% RH), for example by conducting compression strength, bending strength and moisture absorption expansion rate tests on paperboard samples. By analyzing these data, it can be identified that the strength and stiffness of the paperboard significantly decrease under high temperature and high humidity (e.g. 50°C, 90% RH) conditions, which can be determined as the critical environmental condition. Subsequently, the main packaging box type integrated with the cushioning assembly is placed in a constant temperature and humidity chamber simulating the critical environmental condition (50°C, 90% RH) for pretreatment, so as to reach environmental equilibrium. Then, a series of performance tests are conducted on the main packaging box type under the critical environmental condition. For example, drop tests can be conducted to simulate the impact when the main packaging box falls from a certain height; stacking tests can be conducted to simulate the long-term compression when multiple main packaging boxes are stacked; or vibration tests can be conducted to simulate the jolting during transportation. In these tests, the deformation amount of the main packaging box, the crushing condition of the cushioning assembly and the damage degree of the internal items can be monitored, so as to obtain the performance test results. If the performance test results show that the main packaging box fails to meet the preset performance standards under the critical environmental condition, for example, the box body is broken or the cushioning assembly is completely disabled in the drop test, the integration scheme needs to be adjusted in a loop according to the test results. Specifically, the design of the cushioning assembly can be adjusted, for example, if the cushioning assembly is made of corrugated paperboard, it can be considered to increase the height or density of the corrugated flutes, or to use a double-layer corrugated structure; if the cushioning assembly is made of molded pulp, the wall thickness or the layout of the internal reinforcing ribs can be adjusted. In addition, the integration position or fixing method of the cushioning assembly in the main packaging box can also be adjusted to optimize the energy absorption path. After adjustment, the main packaging box type under the new integration scheme is tested again under the critical environmental condition, and so on, until the main packaging box type can stably meet the preset performance standards under the most adverse environment, for example, there is no structural damage in all tests, and the internal items are effectively protected.

[0074] By the technical solution, the problem that the mechanical properties of the carton material are affected by the environmental temperature and humidity, leading to insufficient single-environment verification, can be solved. By obtaining the mechanical property data of the carton material under various temperature and humidity conditions and identifying the critical environmental conditions, it can be ensured that the subsequent performance test is performed under the environment in which the carton material is most vulnerable or most likely to fail. This makes the performance evaluation of the main packaging box type after the integration of the buffer assembly more accurate and covers multiple cases, and can reveal potential structural defects of the main packaging box type under extreme temperature and humidity conditions. Based on the unfavorable test results, the cycle adjustment can comprehensively optimize the design of the main packaging box type, so as to ensure that the main packaging box type can maintain the expected strength, cushioning performance and structural integrity under various actual transportation and storage conditions, including adverse working conditions such as high temperature and high humidity or low temperature and low humidity, thereby avoiding packaging failure and improving the overall stability and adaptability of the main packaging box.

[0075] S5, generating production instructions containing each part of the main packaging box and the buffer assembly.

[0076] The following is described by a specific example to further illustrate the embodiments of the present application. In some preferred embodiments, the present application is implemented as follows. Assuming that an e-commerce enterprise needs to design a new environmentally friendly paper box for aggregating and packaging different sizes of goods on an automated packaging line. First, the system will obtain the instantaneous pressure data applied to the paper box by the mechanical arm when grabbing and placing the goods, and combine the spatial distribution of the goods inside the paper box to identify the key stress areas corresponding to the contact points of the bottom and side walls of the paper box with the mechanical arm by using mechanical simulation software. For example, when the mechanical arm pushes the goods into the bottom of the box, a certain corner of the bottom of the box may bear high pressure. Then, the system will retrieve and screen a plurality of available buffer assemblies, such as paperboard pads with specific corrugated structures or folded structures, from the mold library according to the shape, size and expected impact load of the key stress areas. The design parameters of these pads match the existing molds. Then, the selected buffer assembly, such as a paperboard pad with a honeycomb structure, will be integrated into the key stress area identified on the bottom of the paper box. The integration method can be a pre-set card slot cooperation, so that the buffer pad can undergo controllable crushing deformation when subjected to pressure, thereby absorbing impact energy. Subsequently, the paper box with the integrated buffer pad is subjected to drop test and pressure test to simulate the actual transportation and operation environment. If the test results show that the paper box still has damage risk in the key stress area, the system will adjust the material type, thickness, geometric structure or integration position of the buffer assembly according to the test data, for example, adjusting the honeycomb structure to a more dense grid structure, or increasing the coverage area of the buffer pad, and retesting until the paper box meets the pre-set pressure resistance and impact resistance standards under all test conditions. Once the design is verified, the system will generate production instructions, including the cutting size, folding line of each part of the main body of the paper box, and the production specifications and integration position of the buffer assembly, to guide the automated production line to manufacture.

[0077] In some other embodiments, the application can also obtain the availability status of the existing mold specified in the production instruction, which includes the availability, failure information and wear level of the specified mold; if the availability status of the specified mold is unavailable in the production instruction, the function parameters of the specified mold are obtained, which include the cutting size, supported paperboard type, folding mode and precision level; according to the function parameters of the specified mold, the alternative molds with compatible function parameters in the mold library are identified; if multiple alternative molds are identified, the alternative mold with the minimum deviation from the original production parameters of the specified mold is determined as the preferred alternative mold; based on the operation parameters of the preferred alternative mold, a first revised production instruction containing each part of the main packaging box and the buffer assembly is generated, which contains the number and specific operation parameters of the preferred alternative mold; if no alternative mold is identified, the design parameters dependent on the specified mold in the production instruction are obtained; according to the design parameters, a second revised production instruction containing each part of the main packaging box and the buffer assembly is generated, which contains general processing instructions; the first revised production instruction or the second revised production instruction is output.

[0078] The availability status refers to a set of information that evaluates the extent to which the specified mold is currently available for production, which can be realized by real-time data in the mold management system, manually entered maintenance records or sensor monitoring data, and its purpose is to provide the actual operating condition of the mold.

[0079] The function parameters refer to attributes that describe the technical capabilities and limitations that the mold can achieve during processing, which can be obtained from the specifications recorded in the mold design drawings, technical manuals provided by the mold manufacturer or actual test data, and its purpose is to provide technical basis for the selection of alternative molds.

[0080] The compatible range refers to the allowable degree of difference between the function parameters of the alternative mold and the function parameters of the specified mold, which can be defined by a pre-set tolerance range, industry standards or matching rules based on experience, and its purpose is to ensure that the alternative mold can meet the production requirements.

[0081] The minimum deviation of the original production parameters refers to selecting the mold with the closest production parameters to the original specified mold among multiple alternative molds, which can be realized by parameter value difference calculation, weighted average or multi-dimensional similarity evaluation, and its purpose is to minimize production adjustments and potential product performance impact.

[0082] The preferred alternative mold refers to the mold that is determined to be the most suitable alternative to the original specified mold after screening and evaluation when the mold is unavailable, which can be determined by an automated selection algorithm or manual confirmation, and its purpose is to provide the optimal alternative solution for production.

[0083] The operation parameters refer to the specific settings and control instructions that are required for the alternative mold in actual production, which can be represented by the processing speed of the mold, pressure settings, temperature range, or material feeding rate, etc. The purpose is to guide the production equipment to correctly use the alternative mold. The design parameters refer to the original design information used to guide the redesign or adjustment of the production process to adapt to the general processing mode when there is no suitable mold to replace. It can be represented by product structure size, material properties, performance requirements, or assembly tolerance, etc. The purpose is to provide design basis for general processing. The general processing instructions refer to the guidance information that does not depend on specific molds, but uses general processing equipment and technology to complete the production task. It can be represented by manual operation guide, general numerical control machine tool program, or flexible manufacturing system instruction. The purpose is to ensure the production when there is no specific mold.

[0084] In some preferred embodiments, the present application is implemented as follows: assuming that after generating the production instruction for the master packaging box, the instruction specifies that die A is to be used to produce the cushioning assembly. The system first acquires the availability status of die A. For example, by querying the die management system, it can be found that the availability of die A is shown as “unavailable”, and the fault information is shown as “blade wear is severe”, with a wear level of “high”. Since die A is unavailable, the system acquires the functional parameters of die A, for example, its cutting size can be 200mm x 150mm, the supported paperboard type can be E-type corrugated paperboard, the folding mode can be Z-type folding, and the precision level can be 0.1mm. According to these functional parameters, the system searches for alternative dies in the die library. There can be die B and die C in the die library. The functional parameters of die B can be cutting size 201mm x 150mm, support E-type and F-type corrugated paperboard, folding mode Z-type folding, and precision level 0.12mm. The functional parameters of die C can be cutting size 200mm x 151mm, support E-type corrugated paperboard, folding mode S-type folding, and precision level 0.1mm. The system identifies that the functional parameters of die B and die C are within the compatible range. Further, the system compares the deviation of die B and die C from the original production parameters of die A. Assuming that the deviation of die B in cutting size is 1mm, and the deviation in precision level is 0.02mm; the deviation of die C in cutting size is 1mm, and the folding mode is different. The system can determine that die B has the smallest deviation from the original production parameters of die A, and therefore die B is determined as the preferred alternative die. Based on the operating parameters of die B, for example, its number can be MB002, and specific operating parameters can include cutting speed 500mm / s, and line pressure 100N, the system generates a first revised production instruction containing the parts of the master packaging box and the cushioning assembly. This instruction explicitly indicates the use of die MB002, and is accompanied by its specific operating parameters. As another case, if no alternative die with functional parameters within the compatible range is found in the die library, the system acquires the design parameters in the production instruction that rely on die A, for example, the final shape, size, and required cushioning performance of the cushioning assembly. According to these design parameters, the system generates a second revised production instruction containing the parts of the master packaging box and the cushioning assembly. This instruction can contain general processing instructions, for example, instructing the use of a laser cutting machine for contour cutting, and using manual or general folding equipment for folding, to achieve the required shape and performance of the cushioning assembly. Finally, the system outputs the first revised production instruction or the second revised production instruction generated to the production line, ensuring that production can proceed smoothly even if die A is unavailable.

[0085] Through the above technical solution, the application can dynamically respond to the situation of unavailability of the mold in the production process, and through intelligent identification and selection of alternative molds, or providing general processing instructions when there is no alternative mold, to ensure the smooth execution of the production instructions. This avoids production interruption and delay caused by mold problems, improves the flexibility and continuity of the production line. At the same time, by selecting the alternative mold with the smallest deviation from the original mold parameters, or generating general processing instructions according to the design parameters, the produced buffer components can be ensured to meet the design requirements to the greatest extent, thereby maintaining the performance and quality of the final packaging box, effectively solving the problems of blocked production instruction execution and difficult to guarantee product quality when the mold availability is uncertain.

[0086] The scheme of the application operates through a systematic design process. First, the information of the main packaging box under a specific packaging operation is obtained, and based on this information, the key stress area on the main packaging box that is instantaneously and concentratedly stressed is identified. This identification process is the basis for all subsequent designs, ensuring the pertinence of the buffer design. Second, according to the geometric characteristics and stress characteristics of the identified key stress area, suitable buffer components that can be produced using existing molds are selected from a pre-established mold library. This is aimed at maximizing the reuse of existing design assets and production resources, avoiding unnecessary mold development costs and time. Subsequently, the selected buffer components are integrated into the key stress area of the main packaging box, and their function is to enable these buffer components to absorb the impact energy that the area may bear during the packaging operation, thereby protecting the structural integrity of the main packaging box. On this basis, the main packaging box type with integrated buffer components is verified for performance to evaluate its performance in actual application. According to the results of performance verification, the design scheme will be adjusted and optimized in a loop until the main packaging box type meets the preset performance standards. Finally, when the design scheme is confirmed to meet all requirements, the system will generate production instructions containing each part of the main packaging box and the buffer components to guide the actual production and manufacturing process, ensuring the realization of the design intent. The entire process forms a closed loop from problem identification to solution implementation to performance verification and optimization, ensuring the reliability of the final box type design.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
